Definitions

  • the combining information is transmitted from the second communication device to the first communication device, and a third polarisation is determined based on the combining information.
  • the third polarisation may comprise a polarisation which optimises the signal power received at the second communication device at its current location and orientation, for example at its current arrangement with respect to the first communication device.
  • a payload information signal having the third polarisation is sent via the antenna arrangement of the first communication device. Transmitting the combining information from the second communication device to the first communication device may be in particular advantageously in case a frequency division demultiplexing is used where the uplink and downlink radio channel characteristics may be different and therefore required polarisations in uplink and downlink directions may be different.
